SOM’s proposal was of a handful of plans submitted to transform Grand Central. WXY Architecture and Foster + Partners also submitted ideas.

The Department of City Planning wants to rezone the area around Grand Central, including parts of Park and Madison Avenues, to allow for new office towers and to create pedestrian space, the WSJ reported.

The redesign would help funnel pedestrian traffic and add a bit more glitz and glam to the structure.

The most striking thing about the halo is it would move up and down between the two new office buildings to give visitors views of the city from different heights.

Skidmore, Owings & Merrill's Sky Walk halo design is the flashiest of all the proposed plans.

The halo would give visitors a view of the city from different heights, similar to the London Eye, according to The Wall Street Journal.

In order for any of the plans to receive the go-ahead, first the proposed rezoning will have to be approved. It's still under consideration by the public.

Take a look at the inside the new proposed space.

Inside the halo, you'd get great views of downtown.

As the halo ascends up, there would be a lot of new green space to look down on.
